IMPROVEMENT IN LOCKS FOR DRAWERS, &c.

Specification forming part of Letters Patent No. 138,148, dated April2Q, 1873; application Jiiled November 19, 1872.

To all whoin it may concern:

Be it known that I, EMANUEL G. Gom', of Cincinnati, Hamilton county,State of Ohio, have invented a certain new and useful Improvement inLocks for Drawers or other uses, of which the following is aspecication:

Nature and Objects of Invention.

My invention consists in such aconstruction of the shell or frame of thelock that it is adapted to fasten itself within a routed cavity in thewood, and thus dispense with mortising and with fasteningscrews.

Description of the Accompanying Drawing.

Figure 1 is a perspective view of the pre'- ferred form of my improvedlock. Fig. 2 is a perspective view of a portion of a drawer with arouted cavity adapted to receive the lock shown in Fig. 1. Fig. 3 is amodification in the construction of my improved lock, and Fig. 4 is aperspective view of a portion of a drawer routed out to receive it.Figs. 5, 6, 8, and 9 exhibit modifications in the form of the routedcavity, the locks for each being, of course, made to match. Fig. 7exhibits a routed cavity of rectangular form, intended for the locks,Fig. l or Fig. 3, to be driven into, the frame of the lock cutting itsown way.

General Description.

The mechanism of the lock may be of any preferred construction adaptedfor the form of the shell.

The shell A is so constructed that upon each side of the rear face anextension, projection,`

or wing, a, is formed, which, when snugly tted into a correspondingdepression, b, at each side of the routed cavity B, serves to retain thelock securely in the routed cavity. In`

this way the recess for the reception of the lock for drawers or similaruses, instead of being a mortise necessarily cut by a slowlyoperatingmortising-machine, is an open-sided recess made almost instantly by therapidlyrevolving tool of a routing-machine or 'grooven The tool of therouting-machine may be simply cylindrical, to cut the form of recessshown in Fig. 7, so that the extensions t may cut their own. way intothe sides thereof for selffastening, the extensions a being in that casemade with a cutting-edge, a', or made of short tapering form, as shownin Fig. 3.

This improved form of lock, when driven snugly into a routed cavity suchas described, requires no fastening-screws to hold it in place, andconsequently reduces the expense of the lock and fastenings in additionto the reduced cost of producing the cavity to receive it.
